There is no ZBNF possible in this world now..it was a false thing..its proponent Subash Palekar had already changed to what he calls now as SPNF - Subash Palekar Natural Farming..it is nothing but traditional farming with > 10000 years of history, with some modern understanding based on modern science such as about microbes etc.Farmers here and there are practicing ZBNF/organic farming . Please inform present activity on your farm, as to whether you are taking up seasonal crops or horticultural crops or animal husbandry activities etc.
